    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    Rule: In all normative content (specifications, data schemas, etc.), the deprecated terms “axis” and “dimension” (and their plural or compound forms) MUST NOT be used to denote a measurable aspect. Use Characteristic in the Tech register instead. Other colloquial terms should be mapped to canonical terms as listed below. In Plain narrative, deprecated aliases may appear only on first use and only if paired with their canonical equivalent for clarity.

    Deprecated term (context)Replace with (Tech register)Plain register allowanceCanonical Reference
    axis (of measurement); dimension (of a system or quality)(disallowed in Core prose) → use CharacteristicNo parenthetical allowance in Core; use Characteristic, Measure, or Coordinate onlyA.17 (CHR-NORM)
    point (on an axis); data pointCoordinate (on a Scale)“point” (in explanations only, e.g. “a point on the scale”)A.18 (CSLC-KERNEL)
    metric value; raw scoreCoordinate (or Value)“value” (acceptable in plain usage when context is clear, but formally it’s a Coordinate tied to a Characteristic)A.18, C.16
    score (composite or normalized)Score (produced via a ScoringMethod)“score” (if needed in narrative, ensure it’s explained as a result of a defined ScoringMethod)A.17/A.18 (ScoringMethod/Score)
    unit dimension; unit axisUnit (of a Scale)“unit” (plain usage okay)A.18 (Scale/Unit)
    metric (as a noun)Avoid in Tech and as primitive → use U.DHCMethodRef / U.Measure / Score“metric” (Plain only on first use, with pointer to canonical terms)C.16 § 5.1 (L5), A.18
